DVD player. A DVD player is a device that plays discs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. Some manufacturers originally announced that DVD players would be available as early as the middle of 1996. These predictions were woefully optimistic.
DVD-Video is a consumer video format used to store digital video on DVD discs, and as of 2003 is the dominant consumer video format in Asia, North America, Europe, and Australia. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e. g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below).
